This application is a continuation of U.S. patent application Ser. No. 16/606,386 which is the U.S. national phase of PCT Application PCT/CN2018/083548 filed on Apr. 18, 2016, which claims the benefit and priority of Chinese Application No. 201710267335.3, filed on Apr. 21, 2017, both of which disclosures are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a field of communication technology, and more particularly a method for transmitting information, a terminal and a network device.

BACKGROUND

Compared with the conventional mobile communication system, the future mobile communication system, such as a New Radio (NR) system needs to adapt to more diversified scenarios and service requirements. Main scenarios of the NR mainly include enhanced Mobile Broadband (eMBB), massive Machine Type Communications (mMTC) and Ultra Reliable and Low Latency Communication (uRLLC). These scenarios put forward various requirements, such as high reliability, low latency, large bandwidth and broad coverage, etc. In order to satisfy services and application scenarios of different requirements, a sub-carrier spacing of the NR system is not similar to that of the Long Term Evolution (LTE) system, which adopts a single sub-carrier spacing, i.e., 15 kHz. The NR system may support multiple sub-carrier spacings and different sub-carrier spacings may adapt to different scenarios. For instance, a relative large sub-carrier spacing may be configured for a large bandwidth of high frequency band. In addition, the large sub-carrier spacing may correspond to small symbol length in the time domain, which may fulfill requirements of low latency services.

In the NR technical scheme, the sub-carrier spacing of the system may be 2^(n)*15 kHz. The same carrier may have different sub-carrier spacings. That is, different carrier numerologies may be reused. Different services or different scenarios use corresponding numerology. When the service changes, the NR system changes the numerology according to requirements, so as to make the numerology fulfill the requirements. In addition, since the Uplink (UL) service and Downlink (DL) service may be different, the numerologies of UL links and DL links may be different.

In the Long Term Evolution (LTE) system, the system transmission adopts a fixed sub-carrier spacing of 15 kHz and both the UL and DL data transmission adopts the fixed timeslot length. While in the NR system, the UE may support more than one bandwidth part/frequency range/sub-band, which is called the transmission bandwidth for short in the following sections. Different service data is transmitted on resources corresponding to these different transmission bandwidths. However, different types of service data are not available at all times. Therefore, if the UE simultaneously turns on multiple Radio Frequency (RF) chains, extra power loss will occur.

DETAILED DESCRIPTION

Exemplary embodiments of the present disclosure are described in detail hereinafter with reference to accompanying drawings. Although the accompanying drawings show the exemplary embodiments of the present disclosure, it should be understood that the present disclosure may be implemented via various methods without being limited by the described embodiments. On the contrary, these embodiments contribute to a more thorough understanding of the present disclosure and completely convey the scope of the present disclosure to those skilled in the art of the present disclosure.

Embodiments of the present disclosure provide a method for transmitting information, which is applied to the terminal. As shown in FIG. 1, the method specifically includes following steps.

At step 11, anchor transmission bandwidth information, which is configured by the network device for a terminal, is obtained.

In the communication system, such as the NR system have multiple transmission bandwidths and corresponding terminals also support multiple transmission bandwidths. The transmission bandwidth corresponding to the anchor transmission bandwidth information is at least one of transmission bandwidths supported by the terminal. Further, the transmission bandwidth is also called the bandwidth part, frequency range or sub-band. In other words, the UE may support more than one bandwidth part/frequency range/sub-band, while the service data is not available at all times. Therefore, if the terminal simultaneously turns on multiple Radio Frequency (RF) chains, extra power loss occurs. In order to solve this problem, a network device, such as a base station, e.g., gNB may configure the anchor transmission bandwidth, i.e., the anchor bandwidth part/frequency scope/sub-band, which is called the anchor transmission bandwidth hereinafter for short, for the terminal. The network device transmits the configured anchor transmission bandwidth in the anchor transmission bandwidth information to the terminal. The anchor transmission bandwidth information is used to indicate the anchor transmission bandwidth. Therefore, the terminal only needs to turn on the RF chain corresponding to the anchor transmission bandwidth in the long run, which reduces unnecessary power loss. Embodiments of the present disclosure take the NR system for example and it can be understood that this technical scheme is applicable to the system having the same technical problem. The protection scope of the invention shall be subject to claims and shall not be limited by embodiments or specific terms in embodiments.

At step 12, information is transmitted via transmission resources corresponding to the anchor transmission bandwidth information.

The information transmission mentioned here may be Uplink (UL) transmission or Downlink (DL) transmission. When the network device does not indicate dedicated transmission resources for the terminal, the terminal may transmit or receive the information via the transmission resources corresponding to the anchor transmission bandwidth information.

The step 11 may be implemented via following modes: receiving the anchor transmission bandwidth information, which is configured by the network device for the terminal, via system information, broadcast information, high layer signaling, group common PDCCH or physical layer signaling. The anchor transmission bandwidth may be statically, semi-statically, or dynamically configured. Specifically, when the anchor transmission bandwidth is statically configured, the anchor transmission bandwidth may be defined in protocol or may be obtained via System Information (SI), NR-Primary Synchronization Signal (PSS), NR-Secondary Synchronization Signal (SSS), or broadcast information, etc. When the anchor transmission bandwidth is semi-statically configured, the anchor transmission bandwidth may be obtained via the high layer signaling (such as Radio Resource Control (RRC) signaling), group common Physical Downlink Control Channel (PDCCH), etc. For flexibility, when the anchor transmission bandwidth is dynamically configured, the anchor transmission bandwidth may be obtained via Media Access Control (MAC) Control Element (CE) or physical layer signaling. The physical layer signaling may be signaling in Downlink Control Information (DCI) or group common PDCCH.

The anchor transmission bandwidth information is used to indicate the anchor transmission bandwidth configured by the network device for the terminal. Specifically, the anchor transmission bandwidth information includes: at least one of frequency domain location information, bandwidth information, numerology information and antenna port configuration information of the transmission resources. The numerology is also called the parameter configuration. Sub-carrier spacings, frequency domain resource bandwidths or Cyclic Prefixes (CP) corresponding to different numerologies may be different. Different numerologies may be reused. The numerology information includes at least one of the frequency domain resource bandwidth, sub-carrier spacing and CP.

Further, since the anchor transmission bandwidth information may be fixed, that is, each anchor transmission bandwidth corresponds to a group of fixed frequency domain location information, bandwidth information, numerology and/or antenna port configuration information. In order to reduce the network overhead of the anchor transmission bandwidth information, the anchor transmission bandwidth information may be defined in protocol and each group of anchor transmission bandwidth information corresponds to a fixed and unique index. Therefore, the step for the terminal to obtain the anchor transmission bandwidth information configured by the network device for the terminal may be implemented via following modes: receiving index information, which is configured by the network device for the terminal and transmitted from the network device; and determining anchor transmission bandwidth information corresponding to the index information according to a predefined mapping relationship between the anchor transmission bandwidth information and the index information. That is, the network device notifies the terminal of the index and then the terminal finds the corresponding anchor transmission bandwidth information according to the index.

Further, the anchor transmission bandwidth information may change semi-statically or dynamically. As for the anchor transmission bandwidth information, which changes semi-statically, the network device may notify the terminal of the corresponding relationships between all anchor transmission bandwidth information and indexes. When the anchor transmission bandwidth information of the terminal changes, the network device notifies the terminal of an index corresponding to new anchor transmission bandwidth information, so that the terminal finds the corresponding anchor transmission bandwidth information according to the pre-stored corresponding relationship between all the anchor transmission bandwidth information and the indexes. It's worth pointing out that the above mode, in which the indication is made by index only, is applicable to an application scenario, in which the change period of the anchor transmission bandwidth information supported by the network device is longer than a period of configuring the anchor transmission bandwidth information for the terminal. When the change period of the anchor transmission bandwidth information supported by the network device equals or is shorter than the period of configuring the anchor transmission bandwidth information for the terminal, the above mode, in which the indication is made by index only, is no longer applicable.

The mode for the terminal to obtain the anchor transmission bandwidth information is described hereinafter in the scenario that the change period of the anchor transmission bandwidth information supported by the network device equals or is shorter than the period of configuring the anchor transmission bandwidth information for the terminal. That is, when the change period of the anchor transmission bandwidth information supported by the network device equals or is shorter than the period of configuring the anchor transmission bandwidth information for the terminal, or called when the anchor transmission bandwidth information dynamically changes, the network device needs to transmits the updated anchor transmission bandwidth information to the terminal when the anchor transmission bandwidth information of the terminal changes and the terminal directly receives the updated anchor transmission bandwidth information transmitted from the network device.

Further, the anchor transmission bandwidth information specifically includes: DL anchor transmission bandwidth information and/or UL anchor transmission bandwidth information. Transmission of different scenarios is described hereinafter according to different types of anchor transmission bandwidth information.

When the anchor transmission bandwidth information is the DL anchor transmission bandwidth information, the step 12 specifically includes: receiving, by the UE, the DL information transmitted from the network device via DL transmission resources corresponding to the DL anchor transmission bandwidth information. It is worth pointing out that the applicable scenario is that when the network device does not indicate dedicated DL transmission bandwidth for next transmission or the dedicated DL transmission bandwidth indicated by the network side for the next transmission is the DL anchor transmission bandwidth, the terminal receives UL scheduling information, i.e., UL grant sent from the network device according to DL transmission resources corresponding to the DL anchor transmission bandwidth. There is no need to turn on all supported RF chains, so as to reduce the power consumption of the terminal.

Specifically, the step for receiving the DL information transmitted from the network device via the DL transmission resources corresponding to the DL anchor transmission bandwidth information includes: receiving the UL scheduling information transmitted from the network device via the transmission resources, which are in the transmission resources corresponding to the anchor transmission bandwidth information and are used for transmitting Physical Downlink Control Channel (PDCCH). The UL scheduling information at least indicates first transmission resources scheduled by the network device for the terminal. The first transmission resources include UL transmission resources with an interval of k first transmission time units from the transmission resources corresponding to the PDCCH. The UE transmits data to the network device via the first transmission resources. The first transmission time unit is a transmission time unit corresponding to the UL transmission resources or a transmission time unit corresponding to the DL anchor transmission bandwidth information, k is a positive integer. For instance, it is supposed that Ultra Reliable and Low Latency Communication (URLLC) services of the UE are transmitted on resources with a sub-carrier spacing of f1 and the DL anchor transmission bandwidth information configured by the network device for the terminal corresponds to resources with a sub-carrier spacing of f2, when the UE only has UL URLLC services, the network device may schedule the URLLC services via the transmission resources corresponding to the DL anchor transmission bandwidth information of the UE. As shown in FIG. 2, the UE receives the UL scheduling information via the PDCCH and it is supposed that transmission resources used by the UE for receiving the UL scheduling information are n0. In FIG. 2, the sub-carrier spacing f1 corresponding to Physical Uplink Shared Channel (PUSCH), is 30 kHz, and the sub-carrier spacing f2 corresponding to the anchor transmission bandwidth is 15 kHz. Accordingly, the transmission time unit corresponding to the PUSCH is half of that corresponding to the anchor transmission bandwidth. When the first transmission time unit is based on the larger transmission time unit of the anchor transmission bandwidth, the UL transmission resources scheduled for the UE are n0+k1, k2=2. When the first transmission time unit is based on the smaller transmission time unit of the PUSCH, the transmission resources scheduled for the UE are n0+k2, k2=4.Again, as shown in FIG. 3, the sub-carrier f1 corresponding to PUSCH is 15 kHz, and the sub-carrier f2 corresponding to the anchor transmission bandwidth is 30 kHz. Accordingly, the transmission time unit corresponding to the PUSCH is two times of that corresponding to the anchor transmission bandwidth. The UL scheduling information of UE1 is transmitted on PDCCH1 and transmission resources corresponding to the PDCCH1 are n1. The UL scheduling information of the UE2 is transmitted on PDCCH2 and the transmission resources corresponding to the PDCCH2 are n2. When the first transmission time unit is based on the smaller transmission time unit of the anchor transmission bandwidth, the UL transmission resources scheduled for the UE1 are n1+k3 and the UL transmission resources scheduled for the UE2 are n2+k4, where k3=4, k4=3. When the first transmission time unit is based on the larger transmission time unit of the PUSCH, the transmission resources scheduled for the UE1 are n1+k5 and the transmission resources scheduled for the UE2 are n1+k6, k5=k6=2.

When the anchor transmission bandwidth information is the UL anchor transmission bandwidth information, the step 12 specifically includes: transmitting the UL information to the network device via the UL transmission resources corresponding to the UL anchor transmission bandwidth. It is worth pointing out that the applicable scenario includes: when the network device does not configure dedicated UL transmission bandwidth for the terminal or the dedicated UL transmission bandwidth configured by the network device for the terminal is the UL anchor transmission bandwidth, the terminal transmits the UL information to the network device via UL transmission resources corresponding to the obtained UL anchor transmission bandwidth and needs not to turn on all supported RF chains, so as to reduce the terminal power consumption.

Further, Acknowledgement/Non-Acknowledgement (ACK/NACK) information is a scenario of the UL transmission, which is further described in detail in this embodiment. That is, the step for transmitting the UL information to the network device via the UL transmission resources corresponding to the UL anchor transmission bandwidth information includes: transmitting the ACK/NACK information, which is used to indicate the reception situation of the DL information, to the network device using the transmission resources corresponding to the anchor transmission bandwidth information. It is supposed that the ACK/NACK information is transmitted with the delay of m transmission time units after the data is received, the steps of transmitting the ACK/NACK information, which is used to indicate the reception situation of the DL information, to the network device using the transmission resources corresponding to the anchor transmission bandwidth information includes: determining the transmission resources with an interval of m second transmission time units from the transmission resources, which are in the transmission resources corresponding to the anchor transmission bandwidth information and used to transmit the PDSCH, as the second transmission resources; and transmitting the ACK/NACK information, which is used to indicate the reception situation of the DL information, to the network device via the second transmission resources. The second transmission time unit is a transmission time unit corresponding to the PDSCH or a transmission time unit corresponding to the anchor transmission bandwidth information, m is a positive integer.

Further, the network device determines the value of k or m according to various factors, such as the numerology used by the terminal for transmitting the data, the numerology of the UL anchor transmission bandwidth and processing time of the terminal. As for the Frequency Division Duplexing (FDD) system or (paired spectrum), when the ACK/NACK is transmitted on the UL anchor transmission bandwidth, the numerology of the anchor transmission bandwidth may be fixed or semi-statically configured. Therefore, the time interval m between transmission of PDSCH and ACK/NACK may be fixed or semi-statically configured. Then, m may be defined in the protocol or notified via the SI, broadcast channel, high layer signaling, group common PDCCH, etc. Since m is based on the transmission time units (timeslots) corresponding to the numerologies of different transmission bandwidths and the sub-carrier spacings and transmission time units corresponding to the numerologies of different transmission bandwidths are different, feedback delay m of different terminals may be the same or may be different. Such as, as shown in FIG. 4, both UE1 and UE2 receive data via the same PDSCH, however, resource locations corresponding to the UE1 and UE2 are different (it is supposed that the resource location corresponding to the UE1 is n1 and the resource location corresponding to the UE2 is n2). Suppose the sub-carrier spacing f1 corresponding to the numerology of PDSCH is larger than the sub-carrier spacing f2 corresponding to the numerology of the UL anchor transmission bandwidth (where, in the figure, f1=30 kHz, f2=15 kHz), the transmission time unit corresponding to the PDSCH is half of the transmission time unit corresponding to the UL anchor transmission bandwidth. When the transmission time unit of the PDSCH with smaller transmission time unit is taken as baseline, the transmission resource location corresponding to the ACK/NACK information of the UE1 is n1+m1 and the transmission resource location corresponding to the ACK/NACK information of the UE2 is n2+m2, the value of m1 is different from that of m2, m1=4, m2=3. When the transmission time of the UL anchor transmission bandwidth with larger transmission time unit is taken as baseline, the transmission resource location corresponding to the ACK/NACK information of the UE1 is n1+m3 and the transmission resource location corresponding to the

ACK/NACK information of the UE2 is n2+m4, the value of m3 is the same as that of the m4, 3=m4=2.

For another instance, as shown in FIG. 5, suppose that the sub-carrier spacing f1 corresponding to the numerology of the PDSCH of the transmission data is shorter than the sub-carrier spacing f2 corresponding to the numerology of the UL anchor transmission bandwidth (in the figure, f1=15 kHz, f2=30 kHz), the transmission time unit corresponding to the PDSCH is two times of that corresponding to the UL anchor transmission bandwidth. When the transmission time unit of the PDSCH with larger transmission time unit is taken as baseline, the transmission resource location corresponding to the ACK/NACK information of the UE is n0+m5, m5=2. When the transmission time unit of the anchor transmission bandwidth with smaller transmission time unit is taken as baseline, the transmission resource location corresponding to the ACK/NACK information of the UE is n0+m6 (taking the transmission starting resource as a starting point), or n0+m7 (taking the transmission ending resource as the starting point). The value of m6 is different from m7, m6=4, m7=3.

In the method for transmitting information in embodiments of the present disclosure, the network device configures at least one anchor transmission bandwidth for the terminal, so that the terminal transmits the information via the transmission resources corresponding to the anchor transmission bandwidth information when the terminal does not receive the dedicated transmission bandwidth information indicated by the network device or when the received dedicated transmission bandwidth indicated by the network device is the anchor transmission bandwidth. Therefore, this technical scheme is applicable to a scenario that multiple transmission bandwidths coexist in the NR system. Further, the terminal only needs to turn on the RF link corresponding to the anchor transmission bandwidth information and needs not to turn on multiple RF links, which may reduce power consumption of the terminal.

The above embodiments respectively describe the methods for transmitting information in different scenarios. Terminals corresponding to the above methods are further described in this embodiment accompanying with FIGS. 6 and 7.

As shown in FIG. 6, the terminal 600 in embodiments of the present disclosure may implement the details of the method in the above embodiments, such as obtaining the anchor transmission bandwidth information configured by the network device for the terminal, in which the transmission bandwidth corresponding to the anchor transmission bandwidth information is at least one of transmission bandwidths supported by the terminal, and transmitting the information via the transmission resources corresponding to the anchor transmission bandwidth information, and may achieve the same effects. The terminal 600 specifically includes following function modules.

the UL scheduling information at least indicates that the UL transmission resources with an interval of k first transmission time units from the PDCCH are first transmission resources, the first transmission time unit is a transmission time unit corresponding to the UL transmission resources or a transmission time unit corresponding to the anchor transmission bandwidth information, k is a positive integer.

The first transmission module 620 further includes: a first transmitting sub-module 622, configured to transmit UL information to the network device via UL transmission resources corresponding to the UL anchor transmission bandwidth information when the anchor transmission bandwidth information is the UL anchor transmission bandwidth information.

The first transmitting sub-module 622 includes: a first transmitting unit 6221, configured to transmit Acknowledgement/Non-Acknowledgement (ACK/NACK) information, which indicates a reception situation of DL information, to the network device via the transmission resources corresponding to the anchor transmission bandwidth information when the information transmission is feedback information transmission.

The second transmission time unit is a transmission time unit corresponding to the PDSCH or a transmission time unit corresponding to the anchor transmission bandwidth information, m is a positive integer; and

a first transmitting sub-unit 62212, configured to transmit the ACK/NACK information, which indicates the reception situation of the DL information, to the network device via the second transmission resources.

The anchor transmission bandwidth information includes: at least one of frequency domain location information, bandwidth information, numerology information and antenna port configuration information of the transmission resources.

It is worth pointing out that the terminal in embodiments of the present disclosure obtains the anchor transmission bandwidth information configured by the network device and transmits the information via the transmission resources corresponding to the anchor transmission bandwidth information when the terminal does not receive the dedicated transmission bandwidth information indicated by the network device. This is applicable to a scenario that multiple transmission bandwidths coexist in the NR system. Further, the terminal only needs to turn on the RF link corresponding to the anchor transmission bandwidth information and needs not to turn on multiple RF links, which may reduce power consumption of the terminal.

In order to better achieve the above objective, FIG. 8 is a schematic diagram illustrating structure of a terminal according to another embodiment of the present disclosure. Specifically, the terminal 800 in FIG. 8 may be a cell phone, a tablet PC, a Personal Digital Assistant (PDA) or an on-board computer, etc.

Specifically, in embodiments of the present disclosure, the input unit 830 can include a touch control panel 831. The touch control panel 831, also known as the touch screen, can collect touch operations performed by the user on it or near it (such as operations performed by the user on the touch control panel 831 using any suitable object or attachment, such as a finger, a touch pen, etc.) and drive a corresponding connection device according to preset programs. Optionally, the touch control panel 831 can include two parts, i.e. a touch detection device and a touch controller.

It should be noted that the touch control panel 831 may cover the display panel 841 to form a touch display screen. When the touch display screen detects touch operations on it or near it, the touch display screen transmits the touch operation to the processor 850 to determine the type of the touch event. Then, the processor 850 provides corresponding visual output on the touch display screen according to the type of the touch event.

The touch display screen includes an application interface display area and a common control display area. Arrangement of the application interface display area and the common control display area is not limited and the application interface display area and the common control display area may be arranged in an arrangement mode, which may distinguish the two display areas, such as they may be arranged from top to bottom or from left to right. The application interface display area may be used to display the interface of the application. Each interface may include an interface element, such as an icon and/or widget table control of at least one application. The application interface display area may be an empty interface that does not include any content. The common control display area may be used to display controls with high usage, such as application icons, e.g., a setting button, an interface number, a scrollbar and a phone book icon, etc.

The processor 850 may be the control center of the terminal, connect to each part of the whole cell phone via various interfaces and circuits, execute each function and process data of the terminal to monitor the terminal as a whole via running or executing soft programs and/or modules stored in the first storage 821 and calling data stored in the second storage 822. Optionally, the processor 850 may include one or multiple processing units.

In embodiments of the present disclosure, via calling the software program and/or modules stored in the first storage 821 and/or data stored in the second storage 822, the processor 850 is used to obtain anchor transmission bandwidth information configured by the network device for the terminal, where a transmission bandwidth corresponding to the anchor transmission bandwidth information is at least one of transmission bandwidths supported by the terminal; and, transmit the information via transmission resources corresponding to the anchor transmission bandwidth information.

Specifically, the processor 850 is further used to receive the anchor transmission bandwidth information configured by the network device for the terminal via System Information (SI), broadcast information, high layer signaling, group common PDCCH or physical layer signaling.

Specifically, the processor 850 is further used to receive index information, which is configured by the network device for the terminal and transmitted from the network device; and, determine the anchor transmission bandwidth information corresponding to the index information according to a predefined mapping relationship between the anchor transmission bandwidth information and the index information.

Specifically, the anchor transmission bandwidth information includes: Downlink (DL) anchor transmission bandwidth information and/or Uplink (UL) anchor transmission bandwidth information.

Specifically, when the anchor transmission bandwidth information is the DL anchor transmission bandwidth information, the processor is further used to receive DL information transmitted from the network device via DL transmission resources corresponding to the DL anchor transmission bandwidth information.

Specifically, the processor 850 is further used to receive UL scheduling information transmitted from the network device via transmission resources, which are in the transmission resources corresponding to the anchor transmission bandwidth information and are used to transmit the PDCCH.

The first transmission time unit is a transmission time unit corresponding to the UL transmission resources or a transmission time unit corresponding to the anchor transmission bandwidth information, k is a positive integer.

Specifically, when the anchor transmission bandwidth information is the UL anchor transmission bandwidth information, the processor 850 is further used to transmit UL information to the network device via UL transmission resources corresponding to the UL anchor transmission bandwidth information.

Specifically, when the information transmission is feedback information transmission, the processor 850 is further used to transmit Acknowledgement/Non-Acknowledgement (ACK/NACK) information, which indicates a reception situation of DL information, to the network device via the transmission resources corresponding to the anchor transmission bandwidth information.

Specifically, the processor 850 is further used to determine transmission resources with an interval of m second transmission time units from the transmission resources, which are in the transmission resources corresponding to the anchor transmission bandwidth information and used to transmit the Physical Downlink Shared Channel (PDSCH), as second transmission resources, where the second transmission time unit is a transmission time unit corresponding to the PDSCH or a transmission time unit corresponding to the anchor transmission bandwidth information, m is a positive integer; and, transmit the ACK/NACK information, which indicates the reception situation of the DL information, to the network device via the second transmission resources.

Specifically, the anchor transmission bandwidth information includes: at least one of frequency domain location information, bandwidth information, numerology information and antenna port configuration information of the transmission resources.

The terminal in embodiments of the present disclosure obtains the anchor transmission bandwidth information configured by the network device and transmits the information via the transmission resources corresponding to the anchor transmission bandwidth information when the terminal does not receive the dedicated transmission bandwidth information indicated by the network device. This is applicable to a scenario that multiple transmission bandwidths coexist in the NR system. Further, the terminal only needs to turn on the RF link corresponding to the anchor transmission bandwidth information and needs not to turn on multiple RF links, which may reduce power consumption of the terminal.

The above embodiments describe the method for transmitting the information at the terminal of the present disclosure. One embodiment makes further description of the method for transmitting the information at the network device in combination with figures hereinafter.

As shown in FIG. 9, the method for transmitting the information in one embodiment of the present disclosure is applied to the network device and specifically has following steps:

At step 91, corresponding anchor transmission bandwidth information is configured for the terminal and transmitted to the terminal.

The NR system has multiple transmission bandwidths and the corresponding terminal supports multiple transmission bandwidths. The transmission bandwidth corresponding to the anchor transmission bandwidth information is at least one of transmission bandwidths supported by the terminal.

At step 92, information is transmitted via transmission resources corresponding to the anchor transmission bandwidth information.

When the network device does not configure dedicated transmission resources for the terminal, the network device may transmit or receive the information via the transmission resources corresponding to the anchor transmission bandwidth information.

Further, the step 91 specifically includes: configuring corresponding anchor transmission bandwidth information for the terminal and transmitting the anchor transmission bandwidth information to the terminal via the SI, broadcast information, high layer signaling, group common PDCCH or physical layer signaling. The anchor transmission bandwidth may be statically, semi-statically, or dynamically configured. Specifically, when the anchor transmission bandwidth is statically configured, the anchor transmission bandwidth may be defined in protocol or may be obtained via System Information (SI), such as NR-Primary Synchronization Signal (PSS), NR-Secondary Synchronization Signal (SSS), or broadcast information. When the anchor transmission bandwidth is semi-statically configured, the anchor transmission bandwidth may be obtained via the high layer signaling (such as Radio Resource Control (RRC) signaling), group common PDCCH, etc. For flexibility, when the anchor transmission bandwidth is dynamically configured, the anchor transmission bandwidth may be obtained via physical layer signaling carried in the Media Access Control (MAC) Control Element (CE). The physical layer signaling may be signaling in Downlink Control Information (DCI) or group common PDCCH.

The anchor transmission bandwidth information includes: at least one of frequency domain location information, bandwidth information, numerology information and antenna port configuration information of the transmission resources. The numerology is also called the parameter configuration. Sub-carrier spacings, frequency domain resource bandwidths or Cyclic Prefix (CP) corresponding to different numerologies may be different. Different numerologies may be reused. The numerology information includes at least one of the frequency domain resource bandwidth, sub-carrier spacing and CP.

The network device may indicate the anchor transmission bandwidth information via an explicit indication mode or via an implicit indication mode. The network device in any scenario may indicate the anchor transmission bandwidth information via the explicit indication mode. However, the implicit indication mode should satisfy certain conditions.

Specifically, the implicit indication mode includes: configuring corresponding anchor transmission bandwidth information for the terminal; when the change period of the anchor transmission bandwidth information supported by the network device is longer than the period of configuring the anchor transmission bandwidth information for the terminal, transmitting the index information corresponding to the anchor transmission bandwidth information to the terminal according to the predefined mapping relationship between the anchor transmission bandwidth information and the index information. Specifically, since the anchor transmission bandwidth information may be fixed, that is, each anchor transmission bandwidth corresponds to a group of fixed frequency domain location information, bandwidth information, numerology and/or antenna port configuration information, the anchor transmission bandwidth information may be defined in protocol and each group of anchor transmission bandwidth information corresponds to a fixed and unique index, in order to reduce the network overhead of the anchor transmission bandwidth information. Further, as for the anchor transmission bandwidth information, which changes semi-statically, when the change period of the anchor transmission bandwidth information supported by the network device is longer than the period of configuring the anchor transmission bandwidth information for the terminal, the network device may notify the terminal of the corresponding relationship between all anchor transmission bandwidth information and indexes. When the anchor transmission bandwidth information of the terminal changes, the network device notifies the terminal of the index corresponding to the new anchor transmission bandwidth information.

The explicit indication mode includes: configuring the corresponding anchor transmission bandwidth information for the terminal; when the change period of the anchor transmission bandwidth information supported by the network device is shorter than or equals the period of configuring the anchor transmission bandwidth information for the terminal, directly transmitting the anchor transmission bandwidth information to the terminal. When the change period of the anchor transmission bandwidth information supported by the network device equals or is shorter than the period of configuring the anchor transmission bandwidth information for the terminal, or called when the anchor transmission bandwidth information dynamically changes, the network device directly transmits the configured anchor transmission bandwidth information to the terminal when the anchor transmission bandwidth information of the terminal changes. Further, the anchor transmission bandwidth information includes: DL anchor transmission bandwidth information and/or UL anchor transmission bandwidth information. Transmission of different scenarios is described according to different types of anchor transmission bandwidth information.

When the anchor transmission bandwidth information is the DL anchor transmission bandwidth information, the step 92 specifically includes: transmitting the DL information to the terminal via the DL transmission resources corresponding to the DL anchor transmission bandwidth information. It is worth pointing out that the applicable scenario is that when the network device does not indicate dedicated DL transmission bandwidth for next transmission, the terminal receives DL information sent from the network device according to DL transmission resources corresponding to the DL anchor transmission bandwidth. There is no need to turn on all supported RF chains, so as to reduce the power consumption of the terminal.

Specifically, the step of transmitting the DL information to the terminal via the DL transmission resources corresponding to the DL anchor transmission bandwidth information includes: transmitting the UL scheduling information of the terminal to the terminal via the transmission resources, which are in the transmission resources corresponding to the anchor transmission bandwidth information and used to transmit the PDCCH. The UL scheduling information is used to indicate first transmission resources scheduled by the network device for the terminal. The first transmission resources include UL transmission resources with an interval of k first transmission time units from transmission resources corresponding to the PDCCH. The first transmission time unit is a transmission time unit corresponding to the UL transmission resources or a transmission time unit corresponding to the anchor transmission bandwidth information, k is a positive integer.

When the anchor transmission bandwidth information is the UL anchor transmission bandwidth information, the step 92 includes: receiving the UL information transmitted from the terminal via the UL transmission resources corresponding to the UL anchor transmission bandwidth information. It is worth pointing out that the applicable scenario is that when the network device does not configure dedicated UL transmission bandwidth for the terminal, the terminal transmits the UL information to the network device via the UL transmission resources corresponding to the obtained UL anchor transmission bandwidth and needs not to turn on all supported RF chains, so as to reduce the power consumption of the terminal.

Further, Acknowledgement/Non-Acknowledgement (ACK/NACK) information is a special scenario of the UL transmission, which is further described in detail hereinafter. That is, the ACK/NACK information, which is used to indicate the reception situation of the DL information and transmitted from the terminal, is received via the transmission resources corresponding to the anchor transmission bandwidth information. It is supposed that the ACK/NACK information is transmitted with the delay of m transmission time units after the data is received, the step of receiving the ACK/NACK information, which is used to indicate the reception situation of the DL information and transmitted from the terminal, using the transmission resources corresponding to the anchor transmission bandwidth information includes: configuring the transmission resources with an interval of m second transmission time units from the transmission resources, which are in the transmission resources corresponding to the anchor transmission bandwidth information and used to transmit the PDSCH, as the second transmission resources and receiving the ACK/NACK information, which is used to indicate the reception situation of the DL information and transmitted from the terminal. The second transmission time unit is a transmission time unit corresponding to the PDSCH or a transmission time unit corresponding to the anchor transmission bandwidth information, m is a positive integer.

The network device may determine the value of m according to various factors, such as the numerology used by the terminal for transmitting the data, the numerology of the anchor transmission bandwidth and processing time of the terminal. Since m is based on the numerologies of different transmission bandwidths and the sub-carrier spacings and transmission time units corresponding to the numerologies of different transmission bandwidths are different, feedback delay m of different terminals may be the same or may be different.

In the method for transmitting the information in embodiments of the present disclosure, the network device configures at least one anchor transmission bandwidth for the terminal, so that the terminal transmits the information via the transmission resources corresponding to the anchor transmission bandwidth information when the terminal does not receive the dedicated transmission bandwidth information indicated by the network device or the obtained dedicated transmission bandwidth information indicated by the network device is the anchor transmission bandwidth information. This is applicable to a scenario that multiple transmission bandwidths coexist in the NR system. Further, the terminal only needs to turn on the RF link corresponding to the anchor transmission bandwidth information and needs not to turn on multiple RF links, which may reduce power consumption of the terminal.
